Does Gravel Wash Away?

Which Gravel Washes Away? Gravel can wash away during heavy rains, but proper installation and material selection greatly reduce this risk. Smaller, lighter gravel (like pea gravel) is more prone to washing than larger, heavier stone (like river rock or #57 gravel). Angular crushed stone interlocks and resists movement better than rounded stones. How to Prevent Washout To prevent gravel from washing away: Ensure proper grading so water flows where you want it — not across your gravel surface Install edging along all borders For driveways, create a crown (slight hump in the center) so water drains to the sides Slopes and Drainage On slopes, use crushed stone rather than rounded gravel, and consider installing a geogrid (honeycomb-shaped stabilizer) underneath. French drains or swales can redirect water before it reaches your gravel areas. If erosion is recurring, the underlying issue is usually poor drainage design rather than the gravel itself. Addressing water flow patterns is more effective than simply adding more gravel.

Gravel vs Concrete: Which Is Better?

Gravel and concrete each have clear advantages depending on your priorities, budget, and project requirements. Where Gravel Wins A gravel driveway costs $1-$3 per square foot installed, while concrete runs $5-$10 per square foot. Gravel can be a DIY project; concrete requires professional installation. Gravel is permeable and handles drainage naturally; concrete requires slopes and drainage planning. Where Concrete Wins A properly installed concrete driveway lasts 25-30 years with minimal upkeep. Gravel driveways need periodic regrading, rut filling, and top-layer replenishment. Concrete provides a smooth, clean surface year-round; gravel can be dusty in summer and difficult to plow in winter. Cold Climate Considerations For driveways in cold climates, concrete can crack from freeze-thaw cycles and road salt damage. Gravel handles freezing and thawing without damage but is harder to snow-plow. Which Should You Choose? Choose gravel when budget is a priority, the driveway is long (rural properties), drainage is a concern, or you want a rustic aesthetic. Choose concrete for short suburban driveways, wheelchair accessibility, frequent snow removal, and a modern look.

Crushed Stone vs Pea Gravel: Size, Cost, and Which to Use

Crushed Stone runs about $20 per ton and Pea Gravel about $25 per ton. Compare size, drainage, compaction, and which one to use.

Overview

Crushed Stone

Crushed stone is rock that a quarry blasted, crushed, and screened into a set size range. It costs $20 to $40 per ton in 2026, weighs 1.35 to 1.55 tons per cubic yard, and is the base under nearly every road, driveway, slab, and patio in the country. The important difference from "gravel" in the natural sense is shape: crushed stone is angular, so the pieces lock together, while natural river gravel is rounded and rolls. Almost everything sold as gravel at a quarry is crushed stone.

Pea Gravel

Pea gravel is small, naturally rounded stone screened to 1/4 to 3/8 inch and washed clean. It costs $25 to $50 per ton in 2026, weighs 1.3 to 1.45 tons per cubic yard, and is the most popular gravel for patios, walkways, play areas, and garden beds because it is smooth underfoot and comes in warm mixed colors. The rounded shape is also its main drawback: the pieces do not lock together, so pea gravel shifts, spreads, and needs edging.

Pros & Cons

Crushed Stone

+ Angular pieces interlock and carry weight
+ Cheapest bulk material at $20 to $40 per ton
+ A size for every job, from dust to 4-inch rock
+ Stocked at every quarry
+ Drains (clean) or packs (minus), your choice

− Sharp edges, hard on bare feet and tires in big sizes
− Plain gray look
− Easy to order the wrong size
− Larger sizes are hard to spread by hand

Pea Gravel

+ Smooth and comfortable underfoot
+ Warm mixed natural colors
+ Cheap at $25 to $50 per ton and sold everywhere
+ Drains fast, never muddy
+ Easy to spread by hand

− Shifts and spreads, needs rigid edging
− Ruts under tires
− Hard to push a wheelbarrow or stroller through
− Migrates into lawns and gets thrown by mowers
− Does not pack, so it never firms up

Sizes & Colors

Crushed Stone

Crushed stone is sold by sieve size, from stone dust and #10 screenings (under 1/4 inch) through #8 (3/8 to 1/2 inch), #57 (3/4 to 1 inch), #4 (1 to 1.5 inches), #3 (1.5 to 2.5 inches), and #1 or #2 (2.5 to 4 inches). Every size is angular with fractured faces. Color follows the quarry: gray or blue-gray limestone, gray to pink granite, dark basalt, or tan sandstone and limestone in the South.

Pea Gravel

Pea gravel is naturally rounded stone screened to 1/4 to 3/8 inch, about the size of a garden pea. Because it comes from river and glacial deposits, a load is a mix of colors: tan, brown, cream, gray, white, and rust, with some regional loads running mostly one shade. It is washed, so there are no fines.
